While I have illustrated my improvements as embodied by me in a back cushion for automobiles, it should be understood that it is'capable of a wide range of adaptations. I have not shown these various adaptations as it is believedthat this disclosure will 'enable'those skilled in the art to'embody or adapt my improvements as may be desired.

Having thus described my invention, what I claim as new and Patent is: I
